The markets are at a fulcrum moment, Jim Cramer cautioned his viewers Thursday, one where we could swing 1,000 points up or down.

NEW YORK ( TheStreet) -- The markets are at a fulcrum moment, Jim Cramer cautioned his "Mad Money" TV show viewers Thursday, one where the market could swing 1,000 points up or down. The only problem, we just don't know which direction.

On one side of the lever are the U.S. markets, a market in recovery, one where earnings are rising, as Wal-Mart ( WMT) proved earlier today, and one where the frenzy over Facebook is reaching a fever pitch.

But on the other end of the lever remains Europe, a situation Cramer called "dangerous." He said that people in Greece, Italy and Spain are starting a run on the banks there, taking their money out of the system ahead of what they fear will be a switch from the euro to a currency of far less value. This is a totally rational decision, said Cramer, as Europe has a weak central bank and no U.S.-style TARP program to backstop its banks.

So with a market in flux, a market where investors can't know which way the lever will fall, Cramer said investors must stay diversified. They must also raise cash and they should seek the safety of domestic stocks with little to no exposure to Europe, preferably with dividend protection.

And when it comes to the Facebook IPO tomorrow, Cramer said the only strategy that makes sense is to buy into the IPO and immediately flip those shares as soon as they begin trading.

Executive Decision

In the "Executive Decision" segment, Cramer once again spoke with Marc Benioff, chairman and CEO of Salesforce.com ( CRM), the cloud computing giant that's up 32% for the year.

Benioff touted Salesforce's most recent quarterly results, noting that the company delivered 38% year-over-year revenue growth as well as a healthy increase in the company's cash flow. He said all of their markets were strong, including the ailing European and Japanese markets. "You don't get these kinds of results without all your markets participating," said Benioff.

When asked about how Salesforce stacks up against the competition, Benioff once again noted that business is looking for mobile, social and cloud, three areas on which Salesforce is focused. While other competitors, such as Oracle ( ORCL) and SAP ( SAP), are growing slowly in back-office application software, Salesforce is taking the lead in the front office, helping businesses find customers and close deals.
